MoneySavingExpert.com is a free site - you cannot pay to buy space - one of the reasons why so many people use it! Equally you are not allowed to advertise any goods, services and/or companies anywhere on the forum, or through private messages (PMs), no matter how honourable the intention.
'Advertising' includes touting for business; asking people to contact you; posting e-mail addresses which indicate a web address; linking to sites or blogs you or friends are involved in (whether you’re selling something or not), or to your eBay or other auction sales.
